> The current logic in the TaskTracker and the DataNode to allow a relax version check
with the JobTracker and NameNode works only if the versions of Hadoop are exactly the same.
> We should add a switch to disable version checking completely, to enable rolling upgrades
between compatible versions (typically patch versions).
